manninen Posted November 16, 2019 Share Posted November 16, 2019 Okay long story short, ive had this car since 2011. can achieve 37mpg, reliable and rather stock exterior. S30 body aint designed for low end torque and i can feel something going on, yea sure its best to bring whole body apart and do an rollgage. So strut bars to front and back and lets talk about that rear suspension, there might be something which could to better engine bay i took shape from the hood so i can see clearences, there is some room.

manninen Posted November 16, 2019 Author Share Posted November 16, 2019 I believe those black lines being strongest part on firewall. So this might be good design start to evolve, tube bolted to firewall and something between those. Quote Link to comment Share on other sites More sharing options...
manninen Posted November 16, 2019 Author Share Posted November 16, 2019 (edited) With this one i might gone too far but yeah, orange spots being mustache bar bolts and those four dots, was it four M8 or M10 holding whole rear suspension from rear together. Seems legit, heard no one breaking those though Edited November 16, 2019 by manninen Quote Link to comment Share on other sites More sharing options...
manninen Posted November 16, 2019 Author Share Posted November 16, 2019 (edited) About the suspension, i have bmw limited slip diff, its now hooked to mustache bar. Why not combine mustache bar to transverse links, stock 3part to one part system With this it might be road legal issue here in finland so i have to think about it is it flexing 17:30? Okay these are my thoughts this time Edited November 16, 2019 by manninen Quote Link to comment Share on other sites More sharing options...

The quality of their products looks decent though. Quote Link to comment Share on other sites More sharing options...
manninen Posted November 16, 2019 Author Share Posted November 16, 2019 Yes that suspension conversion looks good but i think im not going with uniballs just yet. https://i.imgur.com/kyOuN1a.mp4 my PU bushings wasnt long joy so im ditching all PU bushings places where is larger movement going on Quote Link to comment Share on other sites More sharing options...
Neverdone Posted November 18, 2019 Share Posted November 18, 2019 I have no idea where you've going with this build, but I'm very excited for you to get there. Quote Link to comment Share on other sites More sharing options...
manninen Posted November 18, 2019 Author Share Posted November 18, 2019 today i received these control arms. Seems decent quality, 4.8kg weight, can be used with stock rubber inner bushings. PU bushings which came installed seems to be softer than energy suspension bushings i had. Outer bushings are tight fit, couldn´t take them off by two fingers. Here´s my only alignment sheet i´ve done. i dont know if left toe comes from worn PU bushings. rear toe might be leveled between left/right by just moving transverse links, cant remember how loose their holes were. Here´s quite similar stuff to 240Z, about toe perspective. I think im going with 2mm toe-in on both axles Quote Link to comment Share on other sites More sharing options...

manninen Posted November 22, 2019 Author Share Posted November 22, 2019 (edited) bought bmw z3 abs unit similar to this, it does have two pipes on front and one for back. pretty old school E30 style. let´s hope theres room for this Edited November 22, 2019 by manninen Quote Link to comment Share on other sites More sharing options...
Neverdone Posted November 22, 2019 Share Posted November 22, 2019 Can you take a photo of how you installed the diff that isn't just a MS Paint version of an old photo? Quote Link to comment Share on other sites More sharing options...
LLave Posted November 22, 2019 Share Posted November 22, 2019 Yikes. Those rear control arms are interesting. That seems like the worst possible location and wrong plane to put flat plate in. Quote Link to comment Share on other sites More sharing options...

That plate doesn't look thick enough to me. Quote Link to comment Share on other sites More sharing options...

With the original E30 computer? I've been exploring ABS a bit but haven't found something very tunable other than the expensive Bosch setup.

That plate doesn't look thick enough to me. yes tell me about it, there is no control arms i like 100%, i chose these cause there is no heim joints. plate is maybe 5-6mm. heaviest part of arm and located on tyre end, no don´t do it like this. Maybe done like this so TTT and apex could not blame copying? 43 minutes ago, calZ said: How are you going to control this? With the original E30 computer?

TUME Posted November 23, 2019 Share Posted November 23, 2019 (edited) There is not so much forces that will bend control arm. Most of the vertical forces are directing to the strut. Control arms get involved mainly lateral forces. So i think those arms are just fine. Btw. is this same car that is some vids from kalajoki @youtube many years ago?

I don't know of anyone who has even looked into the abs controller code, but most of the newer units are flash programmable. As there are only a few manufacturers of abs/stability control systems most cars have the same systems. So if you can collect the program files for number of different vehicles using the same hardware and compare them much like engine ecu tuning you may be able to tune your own abs.

Yes same car, still alive. i got contacted with Toni L. maybe to get some stock part he might not need. and yes theres some flaws on every control arms like TTT, arizona, and apex when u start to look them closer. With this polish arm heavy parts are inner bushing bolts and those outer adjust/bushing parts, arm itself is quite light 3 hours ago, caperix said: I don't know of anyone who has even looked into the abs controller code, but most of the newer units are flash programmable.

Im going with stock code, i have valve for rear brakes. i ´ve had only close call on german autobahn when i had to brake quickly cause of stau, with ABS you can just hit it and wait Edited November 23, 2019 by manninen Quote Link to comment Share on other sites More sharing options...
